In the KB "Panorama", the GIS "Panorama" version 15.2.1 has been developed. The new version includes tools for viewing the 3D geometry of a BIM model of a construction object, building, structure, or complex of construction objects and the associated attribute information of model elements (such as material, article, and others). BIM (Building Information Model) is an object-oriented model consisting of elements, each belonging to its class - walls, floors, windows, reinforcement, and so on. The class of an element defines its set of properties and behavior. The IFC format is supported in this task - an open standard for representing BIM data. To assign a BIM model, it is necessary to select an object on the map and, using the "Select object" dialog on the "Semantic" tab, specify a link to the file (semantics: Link to BIM model file). BIM model viewing is done by double-clicking the left mouse button on a row in the table with this semantics. To view the list of BIM models in the open document, select the option from the main menu - View - List of BIM-models - Show. In this dialog, modes for viewing the BIM model and navigating to the map object to which the model has been assigned are available.

To thematically highlight (colorize) the list of BIM models on the map, it is necessary to select the View - List of BIM-models - Select item from the main menu. Objects on the map will be highlighted, which semantically have a filled link to the BIM model. The style of highlighting (symbolization) of objects can be configured in the View - List of BIM-models - Selection options dialog. When object highlighting with BIM models is enabled, quick selection of the nearest BIM model to the cursor on the map is available. Clicking the left mouse button anywhere on the document will bring up the BIM model viewing dialog. Control of the visibility of the thematic layer of BIM models is performed in the "Map Legend" task on the "General data list" tab.

The "View BIM model" dialog is presented as a 3D image and a tree of model attributes. Scaling of the model is achieved using the mouse wheel, and rotation is done by pressing the left mouse button and moving left, right, up, or down. An element of the model can be selected either in the attribute tree or in the 3D view window of the object. Accordingly, transitioning to the element will result in its subsequent highlighting in the 3D view window and attribute tree.

In the new version of the GIS, the library of programmable symbols shape.iml64 has been enhanced. The sign "Polygon with proportional filling" has been developed. This sign is intended for decorating area structures with a simple outline (without sub-objects). The parameters of the sign contain a description of the average line, central vector sign, and 4 parts of area filling. When entering the parameters of the 1st part, filling of the conditional half of the polygon is performed, bounded by half of the contour (from the first to the middle point) and the average line. When entering the parameters of the 2nd part, filling of the second half of the polygon is performed. If there are parameters for the 3rd and/or 4th parts, filling is done with conditional quarters. The order of filling quarters corresponds to the order of parameters of the 4 parts, starting from the first point, considering the contour numbering direction. Contours with less than 5 or more than 255 points, or with sub-objects, are filled according to the parameters of the 1st part. Sometimes contours containing more than 5 points may intersect with the average line of the polygon. To exclude this effect, it is necessary to select an object on the map, go to the "Metric" tab, select a contour point, click "Set first point", and save the sign. It is recommended to choose a point closest to the center of the sign. Examples of new signs are contained in the shape.sitx map, which can be opened in the main menu: File - Example data - select the map in the folder: c:\Users\Public\Documents\Panorama\Panorama15\data\shape.

The signs "Circular diagram" and "Bar diagram" have been improved. Usually, a legend of

the diagram is drawn to the right of it, containing color samples and labels with values. To exclude drawing the legend, a rule has been introduced: when entering a label height of less than 1 millimeter in the parameters of these signs, drawing the legend is disabled. Examples of such signs are also included in the shape.sitx map: "Simple сircular diagram" and "Simple bar diagram".

A tool for centralized updating of service XML files (coordinate system parameters, quality control parameters, and others) has been incorporated into client workstations for updating or adding these files on the GIS Server. For this purpose, in the Data placement dialogue, the Host field must be filled in with the reference classifiers on the GIS Server. In this field, the host dress is set, where the GIS Server version is not lower than 11.1.0. In the GIS Server Administrator, the Shared folder for classifiers on the server must be filled in. The XML files that will be placed in he shared folder for classifiers on the GIS Server will be automatically updated or added on the client if the GIS Server host is specified. To reduce network load, updates may be delayed by tens of seconds.

The control of the vector map has been refined. When checking object exits to the sheet frame, the range of allowable values for the alignment threshold with the frame has been extended to 0.00001 millimeters of the map. The default value of the alignment threshold is retained at 0.01 mm. Lowering the threshold value enables an improvement in map quality: when conducting control in "Editing" mode, automatic correction of detected errors is carried out.

The task "Correction of objects metrics", which is part of the task group "Check and correction of data", has been improved. In the mode of "Line interpolation with a specified step", the capability to remove original nodes of the object has been added. Following the processing, the object will only contain nodes located at the specified distance from the previous one.

The new version of the program is available for download in the Download section.

In the KB "Panorama", the Complex of Hydrological Tasks version 6.3.5 has been developed for GIS "Panorama" 15, designed for modeling hydrological conditions, constructing flood and drainage zones. The complex has been updated with a set of tools for processing vector objects and digital elevation models (DEM). A mode called "Alignment of Hydrography Objects and Elevation Matrices" has been developed for automatically obtaining hydrologically correct DEMs. The concept of hydrological correctness of DEMs includes the following principles: DEMs should not contain fictitious flow points; flow lines (thalwegs) on DEMs should coincide with the original segments of the river network; the elevation values of DEMs along the flow line should monotonically decrease. When constructing a hydrologically correct DEM, not only relief information but also data on river networks and closed depressions should be taken into account.

The mode "Alignment of Hydrography Objects and Elevation Matrices" processes the hydrography objects of a topographic map as a unified hydrographic network. To obtain a hydrologically correct DEM, the following operations are sequentially performed: searching for nodal points of hydrography objects; dividing hydrography objects at network nodes; stitching hydrography objects that do not have matching nodes at junctions of the network; setting heights for boundary points of linear hydrography objects; setting heights for area hydrography objects with constant elevation (lakes); aligning heights of network nodal points of hydrography; calculating heights of linear hydrography objects; calculating heights of area hydrography objects with variable elevation (rivers). In the absence of elevation coordinates for hydrography objects, values from the DEM are used as initial information for modeling.

A hydrologically correct vector model is used to adjust DEM elevation values. Elements of the matrix receive values from hydrography objects. The height from the metric is transferred to each matrix element that coincides with a point on a linear hydrography object. Heights in matrix elements between metric points are calculated using linear interpolation. Heights in matrix elements within objects with constant water level receive elevation from the object. Heights in matrix elements within area hydrography objects with variable water levels are calculated based on heights of nearest DEM elements with weighted averaging using four directions for interpolation. Subsequently, smoothing of the matrix near hydrography objects is conducted. Only matrix elements related to linear objects and boundaries of area objects are used for smoothing. For each matrix element within the smoothing radius, all matrix elements with aligned heights are found, and their weighted arithmetic mean is calculated based on inverse distances between points as weights. The closer a point with corrected height is to a point with smoothed height, the more influence it exerts on it.

A hydrologically correct DEM is a fundamental element for determining morphometric and hydrographic characteristics of rivers and their basins, including modeling of flooding. Modes for analyzing flooding are included in the complex: "Construction of flood zone by target method", "Construction of flood zone by depths points", and "Construction of flood zone at this point".

The new version of the program is available for download in the Download section.

Geoportal "Bank of spatial data" has been supplemented with a map of the Republic of Guinea-Bissau, formed according to OpenStreetMap data. To work with the map, you can use the GIS Panorama Mini program or other software products of KB "Panorama".

The map was led to the modernised classifier of large-scale plans of scale 1: 5 000 (map5000m). Publishing of updates in bank of spatial data is made by using the program of Databank of digital maps and remote sensing data. Publishing contents of bank of spatial data on the geoportal and data access for downloading are implemented by means of GIS WebServer SE.

Free maps on the basis of OpenStreetMap data are available for download on the page "Digital maps".

In the KB "Panorama", a GIS Server version 11.1 has been developed for the operating systems Astra Linux SE, Ubuntu 18.04, CentOS 8, CentOS 7 and MS Windows. The new version of the program includes support for centralized storage on the server and updates of digital classifiers RSC and service files XML (system coordinate parameters and any other program settings) at client locations. To store files, it is necessary to set up a shared folder for classifiers on the GIS Server using administrative tools and place RSC and XML files there, which will be updated on the client side. Files can be grouped in subdirectories or placed in a single directory. On the client workstation, in the GIS settings, it is necessary to set up a shared folder for classifiers and specify the hostname or IP address of the GIS Server from which RSC and XML files will be updated. Whenever files are updated on the server, the client's GIS will be updated during client operation. To reduce network load, updates can be delayed from several tens of seconds to several minutes based on client settings.

Support for reading and writing shared object lists on the server (files *.obx) has been added for searching, performing overlay operations between lists, and preparing reports. The composition of diagnostic messages has been expanded, and the view of monitoring protocols for the GIS Server's operation status has been enhanced. The procedure for loading data into the Database as part of folders has been improved. When loading folders with the same name but different sets of data, a unique name for the set is generated, including the folder name and the main dataset name.

The GIS Server provides remote access to vector maps, remote sensing data, and spatial databases. Hosting data on the server ensures protection against illegal viewing, copying, modification, and printing. The new version of the program is available for download on the Download page.

In the KB "Panorama", the software complex "Workstation of agronomist" version 15.2 has been developed. In the new version, the range of third-party data sources has been expanded. Additional layers from the Rosreestr geospatial portal are connected - Thematic Maps: Cadastre value of land plots, Land categories, Types of permitted land use, Lands for construction, Lands for tourism.

During land management, thematic maps allow for a quick visual assessment of a particular territory. For example, the map of cadastre value of land plots has 5 gradations: up to 3 million rubles, from 3 to 15 million rubles, from 15 to 30 million rubles, from 30 to 100 million rubles, and over 100 million rubles. Land category map - 8: not established, agricultural lands, forest fund, water fund, specially protected areas, settlement lands, industrial lands, reserved lands. The map of types of permitted land use contains over 220 gradations.

An important set of tools for a GIS specialist in creating infrastructure maps for agriculture is processing lists of objectslists of objects. In the new version of the program, the corresponding dialog has been updated. The ability to cut and split objects belonging to complex lists containing objects from one or several maps opened in one window has been added.

To ensure consistency of symbol libraries on client machines, support for centralized updating of classifiers from the GIS Server has been added. Classifiers located on the server will be automatically updated on the client.

For more flexible data preparation for printing, in the "Map Composition" dialog on the "Numbers" tab, the ability to set a unique object number that will temporarily not be visible on the map has been added.

The new version of the program is available for download in the Downloadsection.
